Checking if socket is still open?

[Markus Pitha]

Hello,
I want to try to program a little server.
I already managed it to send a login message to the connected user, but
I wonder how it works to get information about the connection itself?
With this information, I want to close sockets, which are not in use
anymore (because of quitting by the client).
What's the usual way of programming things like that? I mean, which
return value of which command is usually used for things like that?

I'm using C with Linux.

Standard C has no sockets. Try comp.unix.programmer.

We must do something. This is something. Therefore, we must do this.

this isnt a C question, but rather a question about how to use
sockets. Try comp.unix.programmer, as this is much more ontopic there.
